Winnica chłodzi wino energią z instalacji PV
Właściciele winnicy „La Louvière” na południu Francji wykorzystują energię fotowoltaiczną do chłodzenia wina i utrzymywania go w idealnej temperaturze. Przy temperaturach rosnących latem do +40°C zapotrzebowanie energetyczne winnicy jest bardzo wysokie. Zainstalowany na dachu system fotowoltaiczny o mocy 100 kWp pozwala na pokrycie dużego procenta tego zapotrzebowania z własnej produkcji.
Fronius System Partner Jean-Marc Panizza installed the PV system on seven different roofs at the vineyard, oriented towards three points of the compass. Despite this unusual configuration however, the Superflex Design of the Fronius Symo inverter means that optimum yields are still generated.
The three different roof orientations of the PV system at the vineyard demanded a high level of flexibility in terms of the inverter. The two MPP trackers allow far greater flexibility in how the Fronius Symo inverters are used. The Dynamic Peak Manager means that, even in partially shaded conditions, as is often the case with this type of system, there is no loss of yield. The Dynamic Peak Manager is a shading-tolerant MPP tracking algorithm that does away with the need for a power optimiser in many cases.
Bertrand Moulaire, Sales Manager at Fronius France, comments: “The Superflex Design of the Fronius Symo inverter allowed the installer absolute flexibility in planning the system. The high system voltage at 1,000 volts and broad input voltage range allows installers to add residual modules, for example. As this system shows, different roof orientations do not present a problem.”
The Fronius Symo is very easy to install and also wins when it comes to servicing. PC board replacement technology means Jean-Marc Panizza can carry out a technical service at just one visit, helping to keep long-term costs down. Not only that, Fronius inverters are maintenance-free, again shortening the pay-back time for the system.
